What is the definition of greatest integer function?
The greatest integer function is a function that results in the integer nearer to the given real number. It is also called the step function. The greatest integer function rounds off the given number to the nearest integer.
How do you solve greatest integer function problems?
Here, the values of x can be any real number, and hence the domain of the greatest integer function is ℝ. But observe that all the values of f(x) (y-values) are integers and hence the range is ℤ.

Domain and Range of Greatest Integer Function.
| Values of x | f(x)=⌊x⌋ |
|---|---|
| −7 | f(−7) = ⌊−7⌋ = −7 |
What is the equation for greatest integer function?
The Greatest Integer Function is also known as the Floor Function. It is written as f(x)=⌊x⌋. The value of ⌊x⌋ is the largest integer that is less than or equal to x.
What are the properties of greatest integer function?
Properties of Greatest Integer Function:
[X+Y]>=[X]+[Y], means the greatest integer of the sum of X and Y is the equal sum of the GIF of X and the GIF of Y. If [f(X)]>=I, then f(X) >= I. If [f(X)]<=I, then f(X) < I+1. [-X]= -[X], If X.
Is greatest integer function continuous?
Note that the greatest integer function is continuous from the right and from the left at any noninteger value of x.
What is greatest integer function domain and range?
Domain – The greatest integer function is defined for all real numbers. Hence, as per its definition, its domain is the set of real numbers that are divided into intervals like [−4,3),[−3,2)[−2,1),[−1,0) and so on. Range- Range of the greatest integer function is nothing but all the integers.
What is the range of greatest integer function?
Range- Range of the greatest integer function is nothing but all the integers.
Is greatest integer function always positive?
This function is also known by the names of “floor” or “step” function. The greatest integer function (GIF) is denoted by the symbol “[x]” . Interpretation of Greatest integer function is straight forward for positive number.
What is range of greatest integer function?
Is greatest integer function differentiable?
The greatest integer function is not differentiable at integral points.
Is the greatest integer function discontinuous?
Since L.H.L, R.H.L and the value of function at any integer n∈ are not equal therefore the greatest integer function is not continuous at integer points.
Is the greatest integer function integrable?
You can’t. Since greatest integer functions have infinitely many discontinuous points in a finite closed interval.
Is greatest integer function continuous everywhere?
Is greatest integer function continuous and differentiable?
Greatest integer function isn’t continuous at the integers level and any function which is discontinuous at the integer value, will be non−differentiable at that point. As the value jumps at each integral value, therefore, it is discontinuous at each integral value.
What is greatest integer function in integration?
For any real function, the greatest integer function also known as the Floor Function is represented as ⌊x⌋. The function rounds-off the real number down to the integer less than the number. For example, ⌊-4.010⌋ can be rounds-off as -5.
How do you break the greatest integer in integration?
We just need to check where this greater integer function is discontinous beause those will be the points where we have to break the integration again. Break 1: When varies from 0 to 1 [] value will be 0. Break 2: When varies from 1 to 4 [] value will be 1. Break 3: When varies from 4 to 9 [] value will be 2.
Where is greatest integer function discontinuous?
[Since (2+h) lies between 2 and 3 and the least being 2]
Is the greatest integer function continuous at 0?
The function f(x)=[x], where [⋅] is the greatest integer function defined on R, is continuous at all points except at x=0.
